Answer:
17.2
Step-by-step explanation:
4(a+7) + 2a
4(-1.8 + 7) 2(-1.8)
-7.2+28-3.6
-10.8+28
A: [-8, infinity)
range is the y-values
B, A, C
That's a 30-60-90 triangle.
Answer: 4/5
The slope : rise over run, or the change in y/ change in x
Change in y = 40 (50 - 90)
Change in x = 50 (50 - 100)
40/50 or 4/5
